Note that, before using the algorithmic method as illustrated below, your children should be familiar with the place value strategies that are the basis of the algorithm. For instance, a machine-learning system might compare X-rays of lung tissue in people with cancer and then compare these to whether and how long a patient survived after being given a particular treatment. We even use algorithms to make choices throughout the week. Giving a formal definition of algorithms, corresponding to the intuitive notion, remains a challenging problem.
